Do you know what the polishing method of 2K Plastic mould supplier china is? Let's take a simple look below!
1. Mechanical polishing is a polishing method that removes the polished convex parts by cutting and plastic deformation of the surface of the material to obtain a smooth surface. Generally, whetstone strips, wool wheels, sandpaper, etc. are used, mainly manual operation, and special parts such as the surface of the rotating body , auxiliary tools such as turntables can be used, and ultra-fine grinding and polishing methods can be used for high surface quality requirements. Ultra-precision grinding and polishing is a special abrasive tool, which is pressed on the surface of the workpiece to be machined in the grinding and polishing liquid containing abrasive, and rotates at high speed.
2. Chemical polishing
Chemical polishing is to allow the microscopically protruding parts of the material to dissolve preferentially over the concave parts in the chemical medium, thereby obtaining a smooth surface. The main advantage of this method is that it does not require complex equipment, can polish workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency.
3. Fluid polishing
Fluid polishing relies on high-speed flowing liquid and the abrasive particles carried by it to scour the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet machining, liquid jet machining, hydrodynamic grinding, etc. Hydrodynamic grinding is driven by hydraulic pressure, so that the liquid medium carrying abrasive particles flows reciprocatingly across the surface of the workpiece at high speed. The medium is mainly made of special compounds (polymer-like substances) with good flowability under lower pressure and mixed with abrasives, and the abrasives can be silicon carbide powder.
The above is a brief introduction to the knowledge of polishing methods from 2K Plastic mould supplier china.
